Urchin, Starfish Or Something Else?

Got about 5 pics to post. I found this at the same spot the where my friend found the fish fossil yesterday. It's a poorly preserved concretion and very soft. It's from Washington's Lincoln Creek Formation, early Oligocene. Any ideas?

I would say it is worm tubes that are known as Serpula. They appear to be different diameters which isn't consistent with urchin. A few good specimens can be seen in Ludwigia's photo gallery right here.

Not sure about worm tubes. These seem to radiate outward as if the center has eroded away. Just my cents.

I agree with Tethys that they are some sort of worm, I see a cluster of calcareous tubes of varying diameters. I have seen huge colonies of worms and at any given point they can appear to be radiating outward, inward, or going round in spirals. They just don't have the uniformity for an echinoid.

Thanks everyone. I'm finding a variety of stuff at a new site and some of the finds are unfamiliar. :)
